2. The Who and What SLO Does • Oldest Indiana office, established in 1878 • IDOA division embedded within IDNR • Intent to work closely with DNR Acquisition • Maintains record maps for all state agencies • Excludes INDOT/colleges and universities • Past and present - EAS, DED, CONEAS, WRD • Authority within Indiana on state owned property • Including legal descriptions, surveys, etc. • Over 6,500 deeds Courtesy : http://clearlakeindiana.org/

3. Current Projects • Acquisition - legal approval • Correcting tax parcel information • Boundary verification • QA/QC deeds • Assisting asset management • Healthy Rivers Initiative • Calculating official acreage (owned/managed) • Parcel centralized model for state government • Parcel fabric – production vs publication parcels

4. Beginning SLO version x.1?? • Preserving survey and measurement data • Cogo, line strings (i.e. relative calls) • Integrating attachments • Surveys, supporting documents, etc • Broaden the scale • Not the data model, but part of something larger • Managing restrictions • For acreage calculations • Understanding interests and rights vs acquisition • Other outstanding issues

5. Opportunitas tandem: Parcel Fabric Solution Plans • The Parcel Fabric • Dataset for storage, maintenance and editing of parcels • Historical parcels • Linework adjustment • Coincident geometry • Topology shared across • Production vs publication • Tax Parcels/ CAMA • Public access to data 1 Parcels 1-M 1 1-M Points Lines 1 2-1 1-M 0-1 Control Line Points 1-1 0-M

6. Data Model Themes • There are many…. • Administrative • Related Feature Use • Rights and Interests • Tax Parcels • Boundaries • Corners • Parcel Framework • But, wait! • If you don’t maintain it, you can’t include it!

8. Information Environments Internal Security Parcel production Common Data Resource Internal Pub Web access to data Document Imaging Infrastructure maintenance Firewall To Internet Production Environment Publication Environment

9. Parcel Fabric Excellence in 6 easy steps • 1. Prepare your fabric data model • 2. Prepare the source data – not your production db • 3. Clean up geometry on source data • 4. Establish the topology • 5. Load source data to the fabric • 6. Set up your editing map

10. Don’t go in the woods…..Alone! • Local Government GDB • Visit model here • Parcel Editor ArcMap Add-In • Templates • ESRI’s Tax Parcel Editing (ESRI Resource) • Books/Papers: • GIS and Land Records • By Nancy von Meyer • Loading Data into a Parcel Fabric • ESRI White Paper – April 2011

11. Okay, but where do I start? • Option A: Create a PF from scratch • Good in theory, but not really practical for large data sets. • Option B: Migrate Existing dataset • Load A Topology To a Parcel Fabric Geoprocessing tool • Geometry-based topology with a set of required rules is validated against a subset of selected data or an entire dataset • Import Fabric Data wizard • Imports a formatted dataset of points, lines, and polygons • Same as a COGO coverage. **No longer needs to be formatted into fabric source dataset to be migrated into a parcel fabric as was prior to ArcGIS 10.

13. Migrate: Load A Topology to a PF GP Tool • Requires valid topology • If dataset contains only polygons convert to lines • GP is performance intensive • Limited to under 5K lines • Tools to assist Topo GP • Multipart to Singlepart • Planarize Lines • Split Line at vertices • Topology Rules • Line Feature class: • Must be covered by boundary of polygon feature • Must no self overlap • Must be single part • Must not intersect or touch interior • Polygon Feature class: • Must be covered by boundary of line feature

14. Migrate: Import Fabric Data Wizard • Used to migrate whole datasets • Does need to be formatted into parcel source • Parcel lines • Parcel corner points (nodes) • Parcel polygons • Use PF Source Builder Toolbar • ArcScripts • Data migration process builds fabric parcels using dimensions stored in COGO of source parcel • Some topology also required

15. Editing Environment • Editing Environment • Automatic – tracked via job book • Manual – explicitly define edits

16. Basic Parcel Fabric Editing • Parcel Traverse • Cogo • Line strings (natural boundaries) • Parcel Construction • Traversed, pasted or cogo tools • Parcel Division • Parcel Merge • Remainder Parcel

17. Least Squares Adjustment • 1st run check on control points • All are included in best fit • stored bearings • distances on parcel lines • control points • Repeated until maximum displacement in northings and eastings close to zero • Original COGO not altered

18. SLO Parcel Fabric Parcel Fabric Editing Parcel Fabric Associated 1-1 County Parcels Maintenance Schedules Deeds PLSS Facilities Asset Management Unit Boundaries 1-1 M-1 • Conveyances • Historic • Restrictions • Documents • Leases • Easements 1-1 1-M 1-M Parcel ID

19. Where are we in the process • Still working through process of migration • Nuances in the details • Several trial runs • Half processed • Abridged workflow to QA old, as well as move through new • Determining where production, publication • SDE- DNR/GIO • Multifront approach- asset management, facilities
